Amazon was poised to explore the origin story of Wonder Woman's alter ego Diana of Themyscira. The network announced in September 2012 that it was teaming with Grey's Anatomy's Allan Heinberg to develop the story. The script was redeveloped in May, with Heroes writer Aron Eli Coleite taking a new stab at the story, and the network was poised to take the project to pilot for a potential off-cycle pickup. But that no longer will happen.

"We did not go forward with it," CW president Mark Pedowitz told The Hollywood Reporter following his Wednesday session at the Television Critics Association's winter press tour.

While Amazon will not move forward, Pedowitz was open to taking a second stab at the iconic Wonder Woman character if the right material were to come along.

"It all depends on the script. We were very careful with Arrow, and we're being very careful with Flash," Pedowitz said of the Stephen Amell series and Grant GustinFlash pilot in the works at the network. "These are iconic characters, so we're going to be very careful with Wonder Woman. You only get one shot before you get bit."

Meanwhile, the network is developing DC's Hourman and iZombie with Rob Thomas (Veronica Mars) as it looks to expand its superhero roster. Beyond the youth-skewing network, Fox is prepping Gotham, a Batman prequel focused on Commissioner Gordon; NBC ordered Constantine to pilot; and ABC has found modest success with Marvel's Agents of SHIELD.
